Hi-
I sold a chunk of private company stock this year in a transaction facilitated by a small broker who does not issue 1099-Bs. I'm struggling with how to properly record the cost basis & adjustment. When I enter the actual cost basis (# of shares * exercise price), and then a few screens later enter an adjusted cost basis (# of shares * FMV at exercise date), it then displays "$0" as the cost basis on the "Review your stock sale" screen, which seems to inflate my tax liability since I'm paying capital gains on the WHOLE amount.
If I instead enter the # of shares * FMV at exercise date as the cost basis (box 1e) and then nothing as an adjustment, it shows that as the cost basis on the summary screen, and seems to adjust my tax liability downward accordingly. I can't tell if this is a bug or whether it's somehow going to adjust this later in an AMT section?
